GB/T 31275-2026Assessment of lighting equipment related to human exposure to electromagnetic fields (English PDF)

Foreword

This document complies with the provisions of GB/T 1.1-2020 "Standardization Work Guidelines Part 1: Structure and Drafting Rules of Standardization Documents".

Drafting.

This document supersedes GB/T 31275-2020 "Evaluation of Electromagnetic Radiation from Lighting Equipment to the Human Body" and is consistent with GB/T 31275-2020.

Compared to previous versions, aside from structural adjustments and editorial changes, the main technical changes are as follows.

---The term and definition of "intentional radiator" have been added (see 3.12);

---The general rules for limits have been changed (see 5.1, 4.1 in the 2020 edition).

This document adopts IEC 62493:2022 "Evaluation of electromagnetic radiation from lighting fixtures to the human body".

Compared with IEC 62493:2022, this document has undergone the following structural adjustments.

3.1, Chapter 4 corresponds to 3.2 and 3.3 in IEC 62493:2022.

Please note that some content in this document may involve patents. The issuing organization of this document assumes no responsibility for identifying patents.
